Overview
EN ISO 6806:2024 - Rubber hoses and hose assemblies for use in oil burners specifies minimum requirements for rubber hoses and hose assemblies intended for oil burner installations. Published by CEN as the European adoption of ISO 6806:2024, this edition supersedes EN ISO 6806:2017 and defines construction, dimensions, performance tests and marking for two hose assembly types used with liquid fuel burners.
Key topics and technical requirements
- Hose assembly types
- Type 1: For flux and reflux (not for insertion between pump and atomizer). Maximum working pressure 1.0 MPa (10 bar); max oil temperature 100 °C.
- Type 2: For insertion between oil burner pump and atomizing connection. Maximum working pressure 4.0 MPa (40 bar); max oil temperature 100 °C.
- Construction
- Internally smooth rubber lining with either an external corrosion‑resistant metal braid, or lining + one or more textile/metal reinforcement layers plus rubber outer cover.
- Permanently attached couplings; couplings and metal braid must have suitable corrosion protection and must not adversely affect rubber.
- Dimensions & tolerances
- Nominal inside diameters covered: 5 to 25 mm (sizes follow ISO 1307). Inside diameter and tolerances conform to ISO 1307.
- Minimum bend radii increase with size (e.g., 50 mm at DN 5 up to 165 mm at DN 25).
- Minimum lining thickness 1.7 mm and cover thickness 1.3 mm (measured per ISO 4671).
- Required performance tests
- Hydrostatic tests: proof pressure and burst pressure (ISO 1402).
- Oil swell (ISO 1817), external pressure, low‑temperature flexibility (ISO 10619‑2), flammability, ozone resistance (cover only, ISO 7326) and pressure impulse testing.
- Marking
- Assemblies are marked (examples provided in the standard); marking includes nominal size and other identification required for safe use.
Applications and users
- Practical application: selection, manufacture, testing and installation of rubber hoses used in oil burner systems for buildings, industrial burners and fuel‑oil handling where compliance with pressure, temperature and safety tests is required.
- Who uses this standard:
- Hose manufacturers and assemblers
- HVAC and burner system OEMs and specifiers
- Procurement and quality managers
- Test laboratories, certification bodies and installation contractors

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at

This document was prepared by Technical Committee Technical Committee ISO/TC 45, Rubber and rubber
products, Subcommittee, Subcommittee SC 1, Rubber and plastics hoses and hose assemblies, in collaboration

plastics hoses and hose assemblies, in accordance with the Agreement on technical cooperation between ISO
and CEN (Vienna Agreement).
This fifth edition cancels and replaces the fourth edition (ISO 6806:2017), which has been technically
revised.
The main changes are as follows:
— the normative reference has been updated (Clause 2);
— the normative reference has been updated (7.4);
— the ozone resistance requirement has been modified (7.6);
— the marking has been changed to the nominal size and add example (Clause 10);
— the internal diameter has been changed to the inside diameter (Annex C and Annex D);
— the value of the water pressure has been changed (Annex E);
— the external diameter has been changed to the outside diameter (Annex F).
